In order to enable the robot to find always the right direction, extremely effective, compact laser cameras are used. They are designed for tracking different welding seam types, for identifying and measuring detected gaps, and for online compensation of volumes variations.

The camera design is based on synchronized laser scan technology, featuring high speed stability, large and programmable workspace, deep visual range, and robustness regarding ambient light and reflections. Impassivity against high frequencies and magnetic fields makes it an ideal device for many industrial processes under rough conditions.

The igm laser camera iCAM is mounted on the wrist axis of the robot. It measures the position and volume of the weld groove online and adjusts the robot movement and the welding parameters accordingly. For the application with welding in narrow workpiece ranges, the camera can be automatically deposited and readopted during the welding program. This laser camera iCAM, developed by igm, offers as an outstanding feature the complete integration into the robot control. Thus programming is done with the igm teach pendant K6 without the need for an additional PC. The user benefits from the wide range of languages, European as well as Asian ones, being supported by the robot software. By means of the logging function, the whole joint geometry can be displayed, indicating gaps and volumes. A live view of the measuring field is given by grey scale value image.
